    .travis.runonce.bash: care about exit status

    This excludes msgcheck, because it's over-sensitive and always returns
    exit value which logic I don't remember unless everything is correct
    according to it.

    Oh and the behaviour before this commit allows everything to fail
    without having exit code which shows that it failed and we wouldn't
    notice any failures in near future.

fix .travis.yml

Warnings for .travis.yml:
[x] value for notifications section is empty, dropping
[x] in notifications section: unexpected key on_success, dropping

now:

```
Hooray, .travis.yml looks valid :)
```

Factoids: fix l10n-fi

Fixes #783 (I hope). There is translatable string `$value` that I had
translated and I believe it's what causes that issue.

```diff
 #: config.py:80
  msgid "$value"
  -msgstr "$arvo"
  +msgstr "$value"
